Hi Lily,
Welcome to the Ferret community!
It is possible to create your own palettes, and you may wish to
do that as you get more familiar with Ferret, but a quick way
to make minor changes in your plot using an exisiting palette is by
controlling the levels in your fill or shade plot. Say you are
plotting
a variable and the color key comes out over a range of -5 to 35,
with a delta of 5. Then you could re-do the plot with the levels
starting one notch lower. For example:
yes? use coads_climatology
yes? shade/L=1 sst
! see the levels that were automatically used
yes? shade/lev=(-10:35:5) var
In fact, this is a good example for using the new LEVELS symbols
introduced in version 5.5 of Ferret:
yes? use coads_climatology
yes? shade/l=1 sst
yes? sh sym lev*
LEV_MIN = "-5"
LEV_MAX = "35"
LEV_NUM = "9"
LEV_DEL = "5"
yes? shade/lev=(`($lev_min) - ($lev_del)`, ($lev_max), ($lev_del))/L=1
sst

Hi
all,I am new in using Ferret. I am just wondering how can I fill the graph
with a bit change in the default palette. The default palette start from
purple, which I want to use light blue, and dark blue for the higher value.
All the other color in the palette are fine.Thanks a lot!Lily
